Rotary Spiral Seed Multiplication System

Abstract

The invention discloses a rotary type snail proliferative system, and aims to provide the rotary type snail proliferative system with the advantages of low labor intensity, good releasing uniformity and capability of improving the survival rate of snail fries. The system comprises a stand column arranged on a boat body, a lifting platform frame capable of ascending and descending along the stand column, a lifting execution mechanism used for upward-and-downward moving the lifting platform frame, and an intermittent type self-releasing device arranged on the lifting platform frame and located under the lifting platform frame and at the outer side of the boat body, wherein the intermittent type self-releasing device comprises a fixed partition drum with an horizontally-arranged axis, a movable releasing drum rotatably arranged inside the fixed partition drum through a rotating-shaft rod, and a first drive impeller arranged on the rotating-shaft rod; the rotating-shaft rod and the axis of the fixed partition drum coincide; the lower part of the outside surface of the fixed partition drum is provided with a fixed releasing outlet; and the outside surface of the movable releasing drum is provided with a movable releasing outlet.

Description

technical field [0001] The invention relates to a discharge device, in particular to a rotary snail seed multiplication system. Background technique [0002] Snail marine proliferation and release refers to the fishery method in which snails are artificially propagated and then released into natural ocean waters where snail resources have declined, so that the natural population of snails can be restored, and then reasonable fishing is carried out. [0003] At present, the general method of releasing snails is to pack the seedlings, transport them to the sea area for release by a transport ship, and then manually release the seedlings in a certain sea area. The current artificial snail release method often produces the problem that the discharge is too concentrated, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect. On the other hand, the artificial release method of snail...

AI Technical Summary

Problems solved by technology

The current method of releasing artificial snails often produces the problem of too concentrated release, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect.

On the other hand, the artificial release method of snails is not only labor-intensive and cannot be released in large quantities; but also personnel may fall into the water due to the influence of wind and waves during the release operation, which has certain safety hazards
